LOFAR Deep Fields: Probing faint Galactic polarised emission in ELAIS-N1
Iva Šnidarić, Vibor Jelić, Maaijke Mevius +13
We present the first deep polarimetric study of Galactic synchrotron emission at low radio frequencies. Our study is based on 21 observations of the European Large Area Infrared Sp…
The LOFAR Two-metre Sky Survey -- V. Second data release
T. W. Shimwell, M. J. Hardcastle, C. Tasse +103
In this data release from the LOFAR Two-metre Sky Survey (LoTSS) we present 120-168MHz images covering 27% of the northern sky. Our coverage is split into two regions centred at ap…
The multiphase and magnetized neutral hydrogen seen by LOFAR
Andrea Bracco, Vibor Jelić, Antoine Marchal +4
Faraday tomography of polarimetric observations at low frequency is a unique tool to study the structure of the magneto-ionic interstellar medium (ISM) based on Faraday depth. LOFA…
Foregrounds and their mitigation
Emma Chapman, Vibor Jelić
The low-frequency radio sky is dominated by the diffuse synchrotron emission of our Galaxy and extragalactic radio sources related to Active Galactic Nuclei and star-forming galaxi…
Diffuse polarized emission in the LOFAR Two-meter Sky Survey
C. L. Van Eck, M. Haverkorn, M. I. R. Alves +13
Faraday tomography allows us to map diffuse polarized synchrotron emission from our Galaxy and use it to interpret the magnetic field in the interstellar medium (ISM). We have appl…
Polarized point sources in the LOFAR Two-meter Sky Survey: A preliminary catalog
C. L. Van Eck, M. Haverkorn, M. I. R. Alves +22
The polarization properties of radio sources at very low frequencies (<200 MHz) have not been widely measured, but the new generation of low-frequency radio telescopes, including t…
Polarization leakage in epoch of reionization windows: III. Wide-field effects of narrow-field arrays
K. M. B. Asad, L. V. E. Koopmans, V. Jelić +3
Leakage of polarized Galactic diffuse emission into total intensity can potentially mimic the 21-cm signal coming from the epoch of reionization (EoR), as both of them might have f…
Faraday tomography of the local interstellar medium with LOFAR: Galactic foregrounds towards IC342
C. L. Van Eck, M. Haverkorn, M. I. R. Alves +18
The new generation of low-frequency radio telescopes, such as the Low Frequency Array (LOFAR: a Square Kilometre Array-low pathfinder), provides advancements in our capability of p…
Systematic biases in low frequency radio interferometric data due to calibration: the LOFAR EoR case
Ajinkya H. Patil, Sarod Yatawatta, Saleem Zaroubi +8
The redshifted 21 cm line of neutral hydrogen is a promising probe of the Epoch of Reionization (EoR). However, its detection requires a thorough understanding and control of the s…
Polarization leakage in epoch of reionization windows: II. Primary beam model and direction dependent calibration
K. M. B. Asad, L. V. E. Koopmans, V. Jelić +11
Leakage of diffuse polarized emission into Stokes I caused by the polarized primary beam of the instrument might mimic the spectral structure of the 21-cm signal coming from the ep…
Predictions for the 21cm-galaxy cross-power spectrum observable with LOFAR and Subaru
Dijana Vrbanec, Benedetta Ciardi, Vibor Jelić +8
The 21cm-galaxy cross-power spectrum is expected to be one of the promising probes of the Epoch of Reionization (EoR), as it could offer information about the progress of reionizat…
Effects of the sources of reionization on 21-cm redshift-space distortions
Suman Majumdar, Hannes Jensen, Garrelt Mellema +11
The observed 21-cm signal from the epoch of reionization will be distorted along the line-of-sight by the peculiar velocities of matter particles. These redshift-space distortions…
